Questions
AI-generated answers, 18 Sep 2026
What types of hip surgeries is the Kirschner Self-Tapping Acetabular Cup intended for, and how does its self-tapping feature benefit the procedure?
The Kirschner Self-Tapping Acetabular Cup is designed specifically for total hip arthroplasty, where it serves as a metal acetabular component to replace the damaged hip joint. The self-tapping mechanism simplifies placement by allowing the cup to cut into the bone during insertion, which helps achieve a more stable and secure uncemented fixation within the pelvic acetabulum without requiring additional tools or steps.
How many sizes are available for the Kirschner Self-Tapping Acetabular Cup, and how are they identified?
The cup is available in multiple sizes, each identified by a unique FEI (Final Establishment Identifier) number. There are over 50 distinct FEI numbers listed, ensuring compatibility with a wide range of patient anatomies and surgical requirements. These sizes are critical for achieving proper fit and alignment during total hip arthroplasty.
Is the Kirschner Self-Tapping Acetabular Cup meant for single-use or can it be reused after sterilization?
The device is explicitly labeled as a single-use component and must be handled in accordance with sterile surgical protocols. Reuse is not recommended or supported by the manufacturer, as it could compromise sterility and patient safety.
What regulatory pathway was followed for FDA clearance of the Kirschner Self-Tapping Acetabular Cup, and when was it granted?
The Kirschner Self-Tapping Acetabular Cup received FDA clearance under the Traditional 510(k) pathway, with a decision of Substantially Equivalent (SESE) in 1985. The clearance number is K852351, and it was granted on August 9, 1985, following review by the Orthopedic (OR) Advisory Committee.
How should the Kirschner Self-Tapping Acetabular Cup be stored to maintain its sterility and functionality?
Since the cup is sterile and single-use, it should be stored in its original packaging in a clean, dry environment away from direct sunlight or extreme temperatures. The packaging must remain intact until immediately before use to preserve sterility and ensure the device remains ready for surgical application.
